How Does It Work?

Norpace belongs to a group of medications known as Class I antiarrhythmics; specifically, it is a Class IA antiarrhythmic. Class I antiarrhythmic medications block sodium channels in the heart. This slows down the speed at which electrical impulses move through the heart, which helps stabilize the heart rhythm.

Norpace also prolongs the heart's refractory period, which is the period of time heart cells will not respond to a new electrical signal. By extending the refractory period, Norpace helps the heart tissue resist any electrical signal that is trying to come through prematurely.

Is It Safe for Children to Use Norpace?

Norpace has not been adequately studied in children, and is not approved for use in this age group (usually defined as individuals younger than 18 years old).

However, this does not mean the medication cannot be prescribed for a child. In fact, there are well-established dosing guidelines for the use of Norpace in children. Talk to your child's healthcare provider about the risks and benefits of using this medicine in your child.

Can Older Adults Use It?

There were not enough people over the age of 65 in clinical trials to determine whether older adults will respond any differently to this medicine than younger age groups. However, older adults may be especially sensitive to many of the side effects of Norpace, and may require more careful monitoring and lower Norpace doses.

Off-Label Uses for Norpace

On occasion, your healthcare provider may recommend Norpace for treating something other than the conditions discussed in this article. This is called an "off-label" use. Norpace may be prescribed off-label to treat supraventricular arrhythmias (arrhythmias that begin above the ventricles).
